' To all whom it may concern Be it known that 1, WrLLrAM WHITE, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements" in Round house Equipments, of which the following is a full, clear, and exact description.

The invention relates to round-house v equipments and more particularly to apparatus for conducting the products of combustion from the stacks of locomotives and for inducing draft in the locomotive-furnaces.

In modern locomotive practice, locomotives are frequently run into the roundhouse to be cleaned out and refilled or to be was being put out in the fire-box of the 10- tub comotive, or to connect the exhaust-hood'to the stack and operate the exhausters during that period. A great advantage in time results from inducing draft through the exhauster when firing up. In practice, it is not economical to operate the exhauster when the fires are being put out, which must be done if the usual smoke-jack in the roof of the round-house is dispensed with.

One object of the present invention is to provide an improved connection for a loco motive stack which will serve to either discharge products of combustion from the stack directly'into the atmosphere when the fire is being put out, or to conduct the prodnets to the eXhauster when it is desired to induce draft in the locomotive-boiler in restoring the-locomotive to service condition.

. Another object of the invention is to utilize the exhauster for inducing draft to force the products of combustion through apparatus by which the carbon will be sprayed or dampened so the ffree particles will settle and be collected and not be forced into .the atmosphere.

A further object of the invention is to provide an improved round-house equipment in which the e'xhauster and the supply of water to the washer are 'conjointly controlled, so that the exhauster will not be operated'vvithout the washer and so that the water will not be wasted when the exhauster is not in operation.

Lastly, the invention designs to provide improved apparatus for disposing of the products of combustion from the stacks of locomotives in round-houses and for inducing draft in the fire boxes of the locomotives.

The invention consists in the several novel features hereinafter set forth andmore particularly defined by claims at the conclusion hereof.

1n the drawings: Figure 1 is a perspective of an apparatus embodying the invention. Fig. 2 is an elevation, the round-house being shown in section. Fig. 3 is a vertical longitudinal section, parts being shown in elevar tion. Fig. 4c is a vertical transverse section Fig. 5 is a vertical. section of the washer. Fig. 6 is a detail of the adjustable connection between the motor-control and the water control for'the washer.

10 denotes the roof of the round-house which contains engine-stalls in desired numher, and 11 one of the columns usually dis-' posed between the stalls. A separate ex hausting-apparatus is provided for each stall and comprises an exhauster 14, which ma be of usual construction, and is provide with an inlet-eye l5 and a dischargetrunk 16. An electric-motor 17 is mounted upon a bracket 18 and is directly and operatively connected to drive the blades of the fan, as well understood in the art.

The connection between the exhauster and the stack of a locomotive for conducting the products of combustion from the stack to the eXhauster, comprises an uptake-pipe 19. A flared hood 21,.which is adapted to fit on and make a tight connection with the stackof a locomotive in the stall, is secured to a pipe-section 22 which is telescopically fitted to the pipe 19 so that the hood 21 may be lowered onto the top of a locomotive-stack llO ' wall 25.

" pipe, these cross-walls being separated sufiiciently to permit the uptake-pipe to be swung longitudinally of the stall, so that connection may be made between hood'21 and the stack of the locomotive difierent points in the stall.

The upper terminal of the uptake-pipe extends between and is held against lateral movement by the side-walls 2d of box 24s.

One of the sides of box 24 v has a pipeterminal 28 which is connected to the eye 15 of the exhauster. As a result of this construction, the upper end of pipe 19 is dis posed within and surrounded by the box 24-, so that the pipe itself will hold its terminalwall 25 seated on cross-walls 26 without separate connecting means. This construction also forms a pivotal connection which can be'easily made and which dispenses with. packing-rings. Wall 25 is curved to permit the pipe to swing about a point substantially co-aXial with the inlet-eye of the fan, and the ivotal connection permits, at all times, uno structed passage of the products of combustion to the fan. Box 2a is supported on the roof of the round-house by a base 30 which extends entirely around the box to form a closure between the box and the root and for opening 31 which is formed in the roof of the round-house to permit the uptake-pipe 19 to swing in making connection to the locomotive-stack. The top of the box 24 is formed by a cover or plate 33, which is removably secured thereto by bolts, and is provided with an upwardly extending outlet-pipe 34. By removing plate 33, the box may be easily cleaned when necessary. The upper end of outlet 34 is adapted to be closed by a lid 35, which is pivotally connected at 36 to lugs 37 on said outlet. An arm 38 on the lid and extended laterally to one side of the box,has a pendent chain or cable 39 connected thereto, so that the lid may be opened by the operator in the roundhouse. The weight of lid 35 serves to normally hold it closed, so that when chain 39 is released, the lid will be automatically closed. When it is desired to retain the lid in open position, the lower end of the chain 39 may be fastened by any suitable or con venient means.

The operation of the exhauster 14 by motor 17 is controlled by a switch 40, which may be secured to post 11 or in other con-- venient position in the round-house and is electrically connected to control the operation of the motor by conductors 41 and 42. The switch comprises'a pivoted member 4:3 provided with a handle 44 whereby it may At the opposite sides of the pipe 19 be manually operated. The dischargetrunk 16 of the exhaustcr fan 14- is connected to a smoke-washer ia by a pipe-member 16. This washer comprises a stack or dischargepipe 47 through which the products of combustion from the exhauster will be forced into the atmosphere. A perforated pipe 43 disposed in pipe 16 and connected to a water-supply-pipe 49, is adapted to discharge or spray water into the pipe-member it to dampen the free carbon, and a spraynozzle 50 in pipe 4-7 is-alsoconnected to the water-supply pipe 49 and discharges water intothe discharge-pipe 47. When the exhausteris in operation, the products of combustion willbe drawn through the sprays from the pipe 48 and nozzle 50, so that all of the free carbon and solid particles will be dampened or. soaked, which will cause them to gravitate intothe water outlet or Q receptacle-510i the washer. Receptacle 51, which receives the free carbon and water from the wasl1er,-is connected to a pipe 56, which leads to the sewer. The lower end of receptacle 51; is provided with a trap formed by a bell 53 and the upper end of pipe 56. This trap permits the water and carbon to pass to the sewer and prerents the escape of gases to the sewer. For the purpose of-avoiding waste of water which would result if the water continues to flow through the washer when the exhauster is not in, operation, and to insure the operation of the washer when the exhauster is in operation, the valve 52, which controls the supply of water to the washer, is connected to the switch 43, so that when theswitch is shifted to cause the motor 17 to be operated, valve 52 will be opened to supply water to the washer, and when the snitch is shifted'to discontinue the operation of the motor, the valve 52 will be closed to discontinue the supply of water to the washer. Switch 43 is secured to a shaft 61 which has an arm 62 thereon. The stem of valve 52 is provided with an arm 63 which is connected to arm 62 by a link 64 which is adjustable in length by a turnbuckle 65 so that the connection between the switch and the valve may be adjusted to cause the valve to be open more or less when the switch is closed and to be seated when the switch is open.

The operation of the apparatus will be as follows: When a locomotive enters the round-house under its own steam to be cleaned or repaired, it will be necessary to carry oil the products of combustion from the locomotive stack while the fire is going out. The operator will open'the lid 35 by pulling and fastening down chain 39 and then lowering hood 21 onto the top of the locomotive :stack. I The products of combus tibn, will then pass through'the. uptake 19, box 24 and outlet 35 to the atmosphere.

tit)

will be released so it will close the outlet from box 24. When the locomotive has been cleaned and refilled, and it is desired to quickly restore it to servicecondition and a fire has been built in the fire box of the locomotive, switch l3 will be closed to cause the motor to operate the exhauster and lid 35 will be closed. Thereupon, draft will be induced in the locomotive-boiler and the products of combustion will be carried upwardly through the uptake-pipe 1.9, box 24, exhauster-fan 14 and be discharged into the washer. When the switch 43 is operated to start the exhauster-fan, valve 52 will be opened to supply-water to washer 45 into which the fan delivers the products of combustion. The sprays of Water will cause the free carbon'to be deposited into the member 51, from which they will pass through the trap 59 to the pipe 56 Which leads to the sewer.

The invention thus provides an improved round-house equipment in which a single stack-connection serves to carry off the products of combustion, either directly to the at mosphere when the exhauster is not in operation, or to the eXhauster when it is in operation, thus dispensing with the use of a smoke-jack in addition to the adjustable stack-connection. The equipment also provides an attachment for washing the products of combustion before being discharged in the atmosphere and means for conjointly controlling the exhauster and the washer,

so that waste of water will be prevented and the operation of the washer insured at all times when the exhauster is in operation. The box-connection between the exhauster and the uptake-pipe is one which can be easily constructed and assembled, and provides a simple pivotal connection for permitting the uptake-pipe to be swung into position so its hood will fit on the top of the locomotive stack. The base ofthe box is also utilized to close the elongated opening in the roof in which the uptake-pipe swings. The invention also exemplifies apparatus in which there is a separate exhausting unit for each stall, and separate controlling means for each unit. The invention also exemplifies apparatus in which there is a smoke-washer for each exhausting unit. In practice, it has been found that by employing a separate unit, including a motor and xhauster for each stall, and avoiding so far as possible long connections or conduits and joints in the exhausting connection, the apparatus may be economically operated and will be cflicient in operation to quickly induce the necessary draft inthe locomotive furnace.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
